Worms, whether as live feed or as a meal, are also reported to be highly palatable to aquatic animals. Table 1 shows the high protein content generally found in worms and insect larvae. Several researchers have pointed out the well-balanced amino acid profile of various worm meals, which makes them excellent alternative sources of animal protein to fishmeal in commercial feeds. Research into the use of various types of worms, both as a complete feed or protein supplement, has favorably pointed to their potential for use in aquaculture. These worms can be used as live food, or dried and ground into powder for use in pelleted diets. The use of worms, such as insect larvae, terrestrial earthworms and aquatic oligochaetes, in fish and shrimp rearing has generated considerable interest. However, fishmeal is a finite fishery resource, and the search for novel and renewable sources of protein is crucial for the continued expansion of the aquaculture industry. Much of the protein in commercial aquafeeds is currently being supplied by fishmeal. Protein is the most expensive component in aquafeeds, and it is used in relatively large quantities because of the high protein requirement of most cultured aquatic species. There is an ongoing search for alternative protein sources for use in aquaculture feeds. 1: Mealworm ( Tenebrio molitor) larvae are highly nutritious and palatable to fish. Insect larvae, earthworms and polychaetes gaining interest Fig.
